Editing RIM files

  1. Before you can edit a RIM file, it must be writeable. (meaning not read only)
  2. Select the files in Texconv and select Tools > Check Out Files. (Alternatively, you can right click and choose check out files from the pop up menu). This will create a writeable bitmap or photoshop file in the directory marked as the working path. (Note that this will overwrite any file that already exists under that file name).
  3. Edit the bitmap or photoshop file.
  4. Select the files in Texconv again, and select Tools > Check In Files. (Again, you can right click and choose the option from the menu) .After doing this you will be presented with the transparency / mipmap dialog box again.

If you decide that you didn’t want to check out the RIM file after all, you should use the ‘undo check out’ options.
